    •  DESCRIPTION OF EMBODIMENTS
  • Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Here, components described in the following exemplary embodiments are merely exemplary and not intended to limit a technical scope of the present invention. In the following description, “media information” is the expression to separate part of complex information transmitted in one session, and has a concept including electronic media and digital media. For example, when audio information is separated from video information, a video and a sound are defined as different media information. The media information includes still image data, document data, and sensory data (vibration or the like) as well as a video and a sound.
  • In addition, in the following description, a “session” is a connection unit when seen from a user side, and refers to a series of communication established between a terminal device and a server until the user logs out after the user logs in using the terminal device.
    • First Exemplary Embodiment
  • An information processing system 100 according to a first exemplary embodiment of the present invention will be described with reference to FIG. 1. The information processing system 100 is an information processing system that acquires two or more pieces of media information from at least one server 120, and transmits the acquired media information to two or more terminal devices 141, 142, and 143.
  • The information processing system 100 includes a session control unit 101, a content structuring unit 103, and a transmitting unit 105. The session control unit 101 separates at least one piece of media information from the received two or more pieces of media information based on respective profiles of the terminal devices 141, 142, and 143 in a session established with the server 120. The content structuring unit 103 structures contents to be respectively transmitted to the terminal devices 141, 142, and 143 from at least one piece of media information separated by the session control unit 101. The transmitting unit 105 transmits the contents structured by the content structuring unit 103 to the terminal devices 141, 142, and 143.
  • According to the present exemplary embodiment, information tailored to a terminal device to output can be separated from the two or more pieces of media information received in a session established with the server, and it is possible to provide users of diverse environments with content with a high degree of freedom.
    • Second Exemplary Embodiment
  • An information processing system according to a second exemplary embodiment of the present invention will be described with reference to FIG. 2.
  • The information processing system according to the second exemplary embodiment can satisfy a desire of the user who wants to join a web meeting by a mobile terminal such as a mobile phone, a smart phone, or a mobile PC. Particularly, since the mobile terminal can be carried by the user, the mobile terminal has features that the position of the terminal changes and a peripheral device changes. In addition, communication executed by the mobile terminal is not enough in communication resources and slow in the speed, compared to wired communication. Thus, when communication of rich media such as a web meeting is performed through the mobile terminal, it is difficult to apply a communication function generally implemented in a personal computer (PC) to the mobile terminal as is.
    • For this reason, media filtering according to a profile (a specification or the like) of the mobile terminal needs to be performed between the web meeting application server 210 and the mobile terminal of the user. Meanwhile, since it is possible to support the communication of rich media using another terminal device present in a place to which the mobile terminal has moved, a function which is hardly implemented only by the mobile terminal can be implemented. According to this configuration, it is possible to cause the mobile terminal to function as a remote controller with an ID, and information from the web meeting application server can be output to various terminal devices based on authentication in the mobile terminal.
  • [System Configuration]
  • Referring to FIG. 2, the information processing system 200 is connected to the web meeting application server 210 directly or through a network, and configured to be able to establish a session related to the web meeting application server 210. Meanwhile, the information processing system 200 is also connected to the terminal devices 141, 142, and 143 through routers 221, 222, and 223. Here, since a mobile phone is assumed as terminal device 141, the router 221 performs communication control such that information received from the information processing system 200 is delivered to the terminal device 141 through a mobile carrier network. In addition, a display connected with the Internet at home is assumed as the terminal device 142, the router 222 performs communication control such that information received from the information processing system 200 is delivered to the terminal device 142 through the Internet. Furthermore, since a computer or the like connected to a local area network (LAN) at a meeting room is assumed as the terminal device 143, the router 223 controls communication control such that information received from the information processing system 200 is delivered to the terminal device 143 through the LAN.
  • Meanwhile, the information processing system 200 establishes a session with the web meeting application server 210 using an user identification (ID) or a password acquired from any one of the terminal devices 141, 142, and 143. In other words, the information processing system 200 functions as a relay device that controls information of a session between the web meeting application server 210 and the terminal devices 141, 142, and 143.
  • A detailed internal configuration of the information processing system 200 will be described with reference to FIG. 3. The information processing system 200 includes a managing unit 107 in addition to the configuration of the information processing system 100 according to the first exemplary embodiment. The managing unit 107 includes a profile database 300 and manages profile information of at least one terminal device corresponding to each user on a plurality of users who share contents. The content structuring unit 103 structures a content corresponding to a profile of each terminal device, which is managed by the managing unit 107.
  • In the present exemplary embodiment, the web meeting application server 210 includes a video server 211, a material server 212, and a meeting managing server 213. The meeting managing server 213 is a server that manages information on a meeting participant and so on. The session control unit 101 has a function of separating and multiplexing media information dealt in a session with each server. Particularly, the session control unit 101 selects, separates, or multiplexes necessary information from media information included in a session according to a terminal device based on the profile database 300 managed in the managing unit 107. For example, the session control unit 101 can generate an audio session by separating an audio part from video data received in a session established with the video server 211 using an audio separation software (not illustrated) or generate a frame-advance image session by taking a frame from the video data.
  • The content structuring unit 103 generates data which is to be finally output to the terminal devices 141, 142, and 143 based on the profile database 300. For example, the content structuring unit 103 enlarges image data according to the size or the resolution of a screen of a terminal device of an output destination, converts a stereophonic sound into a monophonic sound according to an audio output specification of a terminal device of an output destination, or compresses various kinds of data according to a communication environment with a terminal device of an output destination.
  • In addition, the transmitting unit 105 can make a virtual private network (VPN) connection with each terminal using a remote desktop protocol (RDP) technique as illustrated in FIG. 3. Meanwhile, for example, when the terminal device 141 is a mobile phone and only a sound output from the terminal device 141 is performed, the content structuring unit 103 may perform codec conversion, and the transmitting unit 105 may output only a sound through a public line. For example, in the information processing system 200, a sound can be output from the mobile phone serving as the terminal device 141, and a video can be output on a screen of a television serving as the terminal device 142. In this case, the managing unit 107 may detect a position relation between the terminal device 141 and the terminal device 142, determine whether or not the terminal device 141 and the terminal device 142 are present at almost the same position, and output information to the terminal device 141 and the terminal device 142.
  • [Profile Database]
  • FIG. 4 is a diagram illustrating an example of content of the profile database 300. In the profile database 300, a plurality of terminal devices are registered for each user ID, and a terminal ID, an IP address (a global IP address or an IP address for a VPN), position information, a specification, a security level, and the like are registered for each terminal device. In the present exemplary embodiment, a screen size, an output color, an output sound, a communication rate, a power state (whether an external power source is a battery), and the like are registered as specifications of a terminal device.
  • The information may be registered one by one on each terminal by the user, or may be set in a way that the user selects a terminal to use from a terminal database in which the position and the specification are registered on a plurality of terminals in advance. The session control unit 101 separates and extracts media information appropriate to an output terminal from a plurality of pieces of media information transmitted in a session with reference to the profile information of each terminal device which is registered as described above. Furthermore, the content structuring unit 103 structures a content with reference to the profile information of each terminal device. For example, when media information with a high security level is acquired from the server, the content structuring unit 103 may perform filtering such that the corresponding media information is not output to a terminal device with a low security level. Alternatively, in order to output information with a high security level to a terminal with a with a low security level, the content structuring unit 103 may apply image processing (a mosaic) to a part of a content.
  • Further, information representing status of terminal devices 1 to 3 is registered in the profile database 300. In the example of FIG. 4, the terminal device 1 and the terminal device 2 are outputting session data, and the terminal device 3 is on standby. Furthermore, the information processing system 200 may sequentially extract information representing whether or not a terminal device is powered on from the terminal device and registers the extracted information in the profile database 300.
  • [Flow of Process]
  • FIG. 5 is a flowchart illustrating the flow of a process according to the present exemplary embodiment. Referring to FIG. 5, first, in step S501, the session control unit 101 starts a session. More specifically, the information processing system 200 performs authentication using an ID and a password input by the user, and then starts a session when the user logs in the web meeting application server 210. Next, in step S502, the information processing system 200 specifies a terminal device (an output terminal) to which data is output during a session. In the case where the session is started by access using a mobile terminal, the information processing system 200 specifies the mobile terminal as a default output terminal. In the case where the session is started by logging in using a PC, the information processing system 200 specifies the PC as a default output terminal. The information processing system 200 may cause a list of information related to other registered terminal devices to be displayed on a screen of a terminal device used to log in based on the profile database 300 so that the user can select an output terminal from the list. Alternatively, a terminal device of an output target be specified in a way that an ID is read from a tag of an RFID or the like labeled on the terminal device in advance by the user's read operation, and the information processing system 200 collates the received ID with the profile database 300.
  • Next, in step S503, the session control unit 101 acquires a profile of the specified output terminal with reference to the profile database 300. Then, in step S505, the session control unit 101 separates and extracts media information in a session according to the profile of the output terminal.
  • In addition, in step S507, the content structuring unit 103 structures a content according to the profile of the output terminal from the media information extracted according to the profile of the output terminal. Then, in step S509, the transmitting unit 105 outputs the structured content to the output terminal using the profile (the IP address or the like) of the output terminal.
  • After content output start, in step S511, the information processing system 200 monitors an instruction to change or add an output terminal. Here, when an instruction to change or add an output terminal is given from the user, the information processing system 200 causes the process to return to step S502, and then specifies an output terminal again. For example, a method of causing the user to specify a plurality of output terminals from a list displayed on the display of the mobile terminal may be used as a method of performing an instruction to change or add an output terminal. Alternatively, the information processing system 200 may change or add an output terminal by activating an RFID reader built in the mobile terminal while the mobile terminal is outputting a sound and by causing the RFID reader to read an RFID originally attached to the display at home, in the meeting room, or the like. Here, when the output terminal is added, a content to be output to an original output terminal may be structured again. For example, when a large screen display is added as an output terminal in a state in which a moving picture, document data, or the like is displayed on a mobile PC, the information processing system 200 may cause the material data to be displayed on the mobile PC and cause the moving picture showing a meeting scene to be output on the large screen display. In reverse, the information processing system 200 releases some output terminals when the user moves to another place from a place in which data is originally displayed on the large screen display.
  • The managing unit 107 may be actively involved change or addition of the output terminal. In other words, for example, the managing unit 107 may trace the position of the mobile terminal serving as the output terminal, and recommend a terminal device present in a place closest to the mobile terminal as an output terminal. On the contrary, the managing unit 107 may be configured to cause a terminal device present in a place far from the mobile terminal not to be selected as an output terminal. For example, there may be used a method of performing a display on the screen of the mobile terminal such that a terminal present in a place far from the mobile terminal is not selected as the output terminal.
  • The process proceeds to step S513 when the process of changing or adding the output terminal is not performed. In step S513, the information processing system 200 determines whether or not an instruction to complete a content output to all output terminals registered by the user has been given or whether or not it is a state in which it is necessary to complete a content output to all output terminals (for example, when all output terminals are powered off).
  • Here, when a content output is not completed, the information processing system 200 causes the process to return to step S511, and repeatedly checks whether or not an output terminal is changed or added. However, when a content output is completed, the information processing system 200 causes the process to proceed to step S515, and performs a process of terminating a session with the web meeting application server 210.
  • According to the present exemplary embodiment, various kinds of sessions in which information is received from various kinds of servers are combined, and thus it is possible to provide users of diverse environments with content with a high degree of freedom.
    • Third Exemplary Embodiment
  • An information processing system 600 according to a third exemplary embodiment of the present invention will be described with reference to FIG. 6. According to the second exemplary embodiment, the information processing system 200 includes the managing unit 107 and the profile database 300 as its internal configuration. However, according to the third exemplary embodiment, the information processing system 600 itself does not include the managing unit 107 and the profile database 300 as its internal configuration. In the third exemplary embodiment, the managing unit 107 and the profile database 300 are managed outside the information processing system 600.
  • Here, when the managing unit 107 and the profile database 300 are provided outside the information processing system 600 as described above, there is an effect by which it is possible to easily deal with an increase in the profile database 300 or the like.
    • Fourth Exemplary Embodiment
  • An information processing system 700 according to a fourth exemplary embodiment of the present invention will be described with reference to FIG. 7. In the second exemplary embodiment, the information processing system 200 includes the managing unit 107 and the profile database 300 as its internal configuration. However, in the fourth exemplary embodiment, the information processing system 700 includes the profile database 300 but does not include the managing unit 107. In other words, in the fourth exemplary embodiment, the profile database 300 is provided as the internal configuration of the information processing system 700 but managed by the managing unit 107 outside the information processing system 700.
  • In this case, the managing unit 107 can be arranged at the position close to the terminal devices 141, 142, and 143, and thus a system in which information representing status or features of the terminal devices 141, 142, and 143 can be easily collected can be configured.
    • Other Exemplary Embodiments
  • The exemplary embodiments of the present invention have been described above, a system or an apparatus in which the separate features included in the respective exemplary embodiments are combined is also included in the scope of the present invention.
  • Further, the present invention may be applied to a system configured with a plurality of devices or may be applied to a single device. In addition, the present invention can be applied even to the case in which an information processing program of implementing the functions according the exemplary embodiment is supplied from to a device directly or remotely. Thus, a program installed in a computer to implement the function of the present invention by a computer, a recording medium (including a continuous recording medium) which can be read by the computer in which the program is stored, and a WWW server that allows downloading of the program are also included in the scope of the present invention.
